Fathom is an educational cross-section model of the Earth with its future super-continental landmass Pangea Ultima, speculated to form in 250 million years. This installation is an extension of Joe Hale's latest work using sculptural models of real and fantastically modified locations to alter the viewers sense of place, and blur the boundaries between fact and fiction. Hale has been heavily influenced by inaccurate historical maps and clocks from revolutionary era France.

The name Fathom is employed for its simultaneous meaning as: an anthropometric unit which is the span across two outstretched arms, to imagine or understand something, and to measure a depth of water. The piece itself has a one-fathom diameter (approximately six feet).
